Transparent window in Tkinter

Last Updated : 19 Nov, 2020

Prerequisite: Python GUI – tkinter

Python offers multiple options for developing GUI (Graphical User Interface). Out of all the GUI methods, tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python.

To create a transparent window, we will use the attributes() method.

Syntax:

root.attributes('-alpha',transparency value)

To create a transparent background, we need to use the -alpha argument in the attributes() method. The alpha is Used for transparency.

If the transparency value is 0.0 it means fully transparent, 1.0 means fully opaque The range is [0.0,1.0]. This isn’t supported on all systems, Tkinter always uses 1.0. Note that in this release, this attribute must be given as -alpha.

Below is a program that creates a normal Tkinter window.

Python3

# Import module
from tkinter import *
 
# Create object
root = Tk()
 
# Adjust size
root.geometry("400x400")
 
# Execute tkinter
root.mainloop()

Output:

Non-transparent Window

Now, the below program creates a transparent window using tkinter module.

Python3

# Import module
from tkinter import *
 
# Create object
root = Tk()
 
# Adjust size
root.geometry("400x400")
 
# Create transparent window
root.attributes('-alpha',0.5)
 
# Execute tkinter
root.mainloop()

Output:
